Whether your paycheck hits your bank account electronically or you get a paper check, your employer may be required to give you a pay stub — sometimes called an earnings statement — every single pay period. Pay stub laws vary by state: some states require them, others don’t. Either way, if you have access to one, use it. A pay stub summarizes how your total earnings were distributed — including taxes paid on your behalf, money deducted for benefits, and what you actually walked away with.
There are two numbers that matter most. Your gross pay is everything you earned before anyone touched it. Your net pay is what actually lands in your pocket after deductions. The gap between those two numbers can be surprising the first time you see it, but it’s not random — every deduction is listed out.
So what gets taken out? A pay stub gives you a detailed breakdown of your income, taxes withheld, and deductions for each pay period. Some deductions are mandatory — you don’t choose them. These typically include federal and state income taxes, Social Security, and Medicare. Others are voluntary, meaning you signed up for them: things like health insurance or a retirement contribution. Each one shows up as its own line item.
Here’s why this matters: mistakes happen. Employers are human. If you never check your stub, you won’t catch it if something’s off — a missing hour, a wrong tax rate, a benefit deduction you didn’t authorize. Your stub is your evidence. The Social Security Administration even lists pay stubs as a primary source of wage evidence when verifying your earnings history through SSA records.
Get in the habit of glancing at it every time you get paid. It takes about 30 seconds once you know what you’re looking at.
